中文摘要：
充分利用建筑物振动变形监测的特点，提出了一种带变形特征及最大变形量约束条件的单历元算法。实例计算证明，该算法可以极大地缩小单历元模糊度搜索空间，减少候选坐标的计算量，有效地提高解算成功率，而且约束尺度越小成功率与效率越高，尤其是加入以平面或竖直方向变形为主的变形特征约束时，单历元算法的效率越为明显。
英文摘要：
On the basis of the GPS single epoch solution algorithm in attitude determination application, another GPS single epoch solution algorithm using the max deformation size and deformation characters constraints combined with Cholesky decomposition method in deformation monitoring application is developed. The ambiguity search space is set up directly in this arithmetic and it will become very small if there is only horizontal or vertical deformation. From the GPS test, it shows that the methods is very efficient, and the success rate is also improved expansively.
